Description

Technical Field

[0001] The utility model relates to a chain jacquard machine with a chain capable of being lubricated in an oil bath, belonging to the technical field of jacquard machine shedding equipment. Background Art

[0002] The most common chain jacquard machine configuration on the market today features an open-type transmission sprocket and chain mounted on one side of the wall panel. The chain drive is described in patent publication number CN101476190A for its detailed structure. This type of open-type chain requires regular manual grease lubrication. Grease has poor fluidity, with limited flow between the chain rollers and the sleeve. Iron filings released by friction between the chain and sprocket mix with the grease and participate in friction. Furthermore, dust and lint from the open-type transmission can contaminate the grease. Grease spillage can also cause internal and external contamination of the equipment, and even contaminate the woven product.

[0003] In view of the above, how to effectively lubricate the chain and seal the lubricating oil is an urgent problem to be solved. Utility Model Content

[0004] The utility model aims to solve the above-mentioned problems and further provides a chain jacquard machine whose chain can be lubricated in an oil bath.

[0007] A semi-enclosed box is provided on one side of the wall panel to enclose the power component. The end face of the semi-enclosed box is provided with an upper cover plate and a lower cover plate that are detachably connected thereto, and the lower cover plate is sealed to the lower half of the semi-enclosed box to form an oil storage chamber for filling lubricating oil.

[0008] Furthermore, an oil mirror is provided on the lower cover plate to observe the lubricating oil level inside the oil storage cavity.

[0009] Furthermore, the lower cover is sealed and connected to the lower half of the semi-enclosed box through an oil-resistant sealing gasket or an oil-resistant gasket-free sealant.

[0010] Furthermore, the upper cover plate and the lower cover plate are two independent cover plates that are respectively fixedly connected to the end surfaces of the semi-enclosed box.

[0011] Furthermore, the upper cover plate and the lower cover plate are movably connected via a hinge.

[0012] Furthermore, the transmission assembly includes a driving sprocket, two shed sprockets and a tensioning sprocket connected by a transmission chain, and the driving sprocket is driven and connected by a main transmission shaft.

[0013] Furthermore, both ends of the main transmission shaft pass through the two side wall panels respectively and are fixedly connected to the driving sprockets on the corresponding side wall panels.

[0014] Furthermore, the lubricating oil level in the oil storage chamber should be ensured to submerge at least some of the links of the transmission chain.

[0015] Furthermore, both sides of the wall panel are fixedly connected to the inner side surfaces of the frame respectively.

DETAILED DESCRIPTION

[0022] The present invention is described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] A chain jacquard machine with oil-bath lubrication comprises a frame 1, a pair of wall panels 2 mounted on the frame 1, and a power assembly mounted on the wall panels 2. Both wall panels 2 are cast from gray cast iron. The wall panels 2 and the power assembly mounted on one side of the wall panels have identical structures. The power assembly comprises a main transmission shaft 7, a driving sprocket 4, a shed sprocket 5, a tensioning sprocket 8, and a transmission chain 6. The main transmission shaft 7 extends through both wall panels 2 at both ends and is fixedly coupled to the driving sprocket 4 on the corresponding side wall panel. Two shed sprockets 5 are juxtaposed and mounted on corresponding shed wheels 3. The shed wheels 3 are rotatably mounted on the wall panels 2 via bearings. The tensioning sprocket 8 is located below the two shed sprockets 5. The transmission chain 6 connects the two shed sprockets 5, the tensioning sprocket 8, and the driving sprocket 4 to form a transmission chain.

[0025] A semi-enclosed box 10 covering the transmission assembly is provided on one side of the wall panel 2. The outer side of the semi-enclosed box 10 is correspondingly adapted with an upper cover plate 11 and a lower cover plate 12 distributed up and down. The upper cover plate 11 and the lower cover plate 12 are independent panels, and are fixedly mounted to the end face of the semi-enclosed box 10 via a detachable connection structure. In particular, the lower cover plate 12 is sealed to the lower half of the semi-enclosed box 10 via an oil-resistant sealing gasket or an oil-resistant gasket-free sealant to form a sealed oil storage chamber to prevent oil leakage; the lubricating oil level in the oil storage chamber should be sufficient to submerge some of the links of the transmission chain 6. At the same time, in order to facilitate observation of the oil level inside the oil storage chamber, an oil mirror 13 is provided on the lower cover plate 12. In order to facilitate adjustment of the tensioning sprocket 8, an adjustment window is provided at a predetermined position of the lower cover plate 12. It is understandable that in this embodiment or other embodiments, the upper cover 11 can also be sealed and connected to the upper half of the semi-enclosed box 10 through an oil-resistant sealing gasket or an oil-resistant gasket-free sealant to ensure that the transmission component has better sealing.

[0026] In this embodiment, the two sides of the wall panel 2 are fixedly connected to the inner side surfaces of the frame 1 respectively. Compared with the traditional fixing method of fixing the bottom surface of the wall panel 2 to the upper end surface of the frame 1, the upper end processing surface of the frame 1 can be saved, thereby saving manufacturing costs.

[0027] In this embodiment, a slider 15 made of nylon is installed on the broaching frame plate 14 through a rotating shaft 16, and guide grooves 9 adapted to the slider 15 are provided on both sides of the corresponding wall panel 2. When the broaching frame plate 14 moves, it drives the slider 15 to slide up and down in the guide groove 9 on the wall panel 2.

[0028] Compared with similar products, the chain jacquard machine of this utility model has the following advantages:

[0029] 1. Add a box on the outside of the wall panel to improve the strength of the wall panel.

[0030] 2. Add a box on the outside of the wall panel to enclose the transmission components, and seal the box with a cover to reduce the contamination of the lubricating oil by external dust and lint, and also prevent the spillage of lubricating oil from causing pollution to equipment and products.

[0031] 3. Add a box on the outside of the wall panel and seal the box with a cover to form an oil storage space. Fill the oil storage space with lubricating oil with better fluidity and immerse part of the chain in the oil. The oil can quickly flow into the space between the rollers and sleeves of the chain, effectively improving the lubrication effect, reducing the wear of the chain rollers and sleeves, and reducing the iron chips generated by transmission friction.

[0032] 4. Lubricating oil can be replaced regularly, which greatly reduces the frequency of maintenance (grease should be replaced once a week, and lubricating oil once every six months), and avoids abnormal wear caused by untimely manual maintenance.

[0033] 5. The iron filings dropped by the friction between the chain and sprocket will fall into the lubricating oil, which will clean the chain to a certain extent and reduce the wear of the chain.
